There should be- I disabled that option in my privacy settings...
I guess if it's there...
But I wouldn't know how.

Should we have a Dr. Seuss week around Dr. Seuss' birthday? yikes
I love him!

I loved those books. Loved loved loved loved them. When I was four, I'd pretend to be able to read "Mr. Brown", when I'd really only memorized the words.

I like the poem, maths, but I noticed that eye and symmetry don't rhyme...

I think calculus sounds fun! A lot of the stuff we do in my math class is just plugging things into formulas we learned two years ago. I'm ready to learn something new.
Bwahahaa.
I want to get through AP Calculus III/IV before graduating highschool. WOOH! That class will be AWESOME!

Happy for the warm welcome, too!
Haha, and about my avatar, it's a www.potterpuppetpals.com thing. It makes me laugh. tongue
Well, I definitely am hoping to learn things...

So you're saying that a lot of the junk we're learning that I don't think has anything to do with anything will become useful?
I think we could've skipped the unit about "How to determine if a question is biased."
That seemed like a journalism thing to do...

And I love your signature!

Uhmm... I think I've heard this one before. I don't remember if this is right, but it has something to do with speaking it out loud.
I'm going to guess..

Heya! I'm Andrea, ninth grader, taking Algebra III/IV. I came to this website looking for a way to solve an equation that actually couldn't be solved manually... drove me crazy. At least I found out it didn't need to be solved.
I'm usually not very active on forums I used to sign up at, but that was a year ago, and maybe now I'll be a bit better at keeping up with everything going on here. Looks like I could have lots of fun on this website learning the stuff my teachers won't teach me. tongue
See you soon. smile

Mehehehe... if your in algebra III/IV your in algebra 0.75.

I'm curious, what exactly does one learn in algebra 3 and 4 that you don't learn in calculus? I thought algebra only went as high as 2, then precalc (Aglebra 3?) then calculus and beyond. Didn't know there was algebra 3 and 4. Interesting.

Haha, .75. Wooh, I must be in the CT class.
I think it's different with different schools. At my school, the first year of algebra is algebra I/II, semesters one and two.
Then you take Geometry.
Then you go back and take algebra III/IV.
I'll be taking pre-calc next year.
I don't understand why we have to split up the algebra classes. I think we could be in precalc already, as a lot of the stuff we've done in algebra this year was just re-learning what we already knew in Algebra 1.
I don't think many people in my class noticed that, though... Many people didn't understand much.

There is no way to (mathematically) explicitly solve for x.  This is the case for many equations.  You can, however, use computer algorithms to approximate a solution.  This is what graphing calculators do.

Oh, and if you didn't know, explicitly solving for x means:

x = ____________

Where that blank does not contain x.  If an equation is not explicit, it is called implicit.

Oh, thank you!
That must be why the book had nothing about it.
Unsolvable, gotcha.
Thanks muchly.
